Common NameDynorphin B
DescriptionDynorphin B, also known as rimorphin, belongs to the class of organic compounds known as polypeptides. These are peptides containing ten or more amino acid residues. Goldstein et al. Applied the synthetic peptide to the guinea ileum longitudinal muscle and found it to be an extraordinarily potent opioid peptide. Dynorphin B is a very strong basic compound (based on its pKa). When prodynorphin is cleaved during processing by proprotein convertase 2 (PC2), multiple active peptides are released: Dynorphin A, dynorphin B, and a/b-neo-endorphin. Dynorphins are stored in large (80-120 nm diameter) dense-core vesicles that are considerably larger than vesicles storing neurotransmitters.
